solution to this question physics formula what is the corect temperature ? when it reads 50 degree celsius , of a faulty celsius thermometer reads 1.2 degrees celsius at the melting piont of pure ice and 85.6 degree celsius at steam piont of water at normal pressure . At what temperature will its reading be exactly correct
To find the correct temperature when the faulty Celsius thermometer reads 50 degrees Celsius, we need to calibrate it based on the known reference points of the thermometer.
1. Deduct the error at the melting point of pure ice:
The thermometer reads 1.2 degrees Celsius at the melting point of pure ice, which is 0 degrees Celsius. So, the error at this point is 1.2 degrees Celsius (positive, as the thermometer reads higher than the actual temperature).
50 degrees Celsius - 1.2 degrees Celsius = 48.8 degrees Celsius
2. Deduct the error at the steam point of water at normal pressure:
The thermometer reads 85.6 degrees Celsius at the steam point of water at normal pressure, which is 100 degrees Celsius. So, the error at this point is 14.4 degrees Celsius (negative, as the thermometer reads lower than the actual temperature).
48.8 degrees Celsius - 14.4 degrees Celsius = 34.4 degrees Celsius
Therefore, the reading would be exactly correct at a temperature of 34.4 degrees Celsius.
